Oral administration of herbal oligonucleotide drug JGL‐sRNA‐h7 ameliorates hyperglycemia in db/db mice and beagle dogs

Abstract

AbstractType 2 diabetes mellitus is a prevalent metabolic disease, posing a considerable threat to public health. Oligonucleotide drugs have proven to be a promising field of therapy for the diseases. In this study, we reported that a herbal small RNA (sRNA), JGL‐sRNA‐h7 (B34735529, F1439.L002444.A11), could exhibit potent hypoglycemic effects by targeting glucose‐6‐phosphatase. Oral administration of sphingosine (d18:1)‐JGL‐sRNA‐h7 bencaosomes ameliorated hyperglycemia and diabetic kidney injury better than metformin in db/db mice. Furthermore, glucose tolerance was also improved in sphingosine (d18:1)‐JGL‐sRNA‐h7 bencaosomes‐treated beagle dogs. Our study indicates that JGL‐sRNA‐h7 could be a promising hypoglycemic oligonucleotide drug.
